Two new climate zones (0A/B) have been added to all prescriptive requirements tables.īuilding Envelope Envelope verification in support of reduced air infiltration and increased requirements for air leakage of overhead coiling doors. Section 5.1.4 now cites ASHRAE Standard 169 as the source for climatic data, and Annex 1 contains extracts of tables and figures from that standard for the readers convenience. Structural changes: A new Reference Standard Reproduction Annex 1 is provided at the end of the document. It also includes the following:įormat changes to improve usability and readability: One-column format for easier reading Exceptions separated, indented, and set apart with a smaller font size Italicized defined terms Changes to table formats to provide contrast between rows This 2016 edition comprises numerous energy-saving measures and incorporates changes from more than 125 addenda. It is an indispensable reference for engineers and other professionals involved in design of buildings and building systems. It offers, in detail, the minimum energy efficiency requirements for design and construction of new buildings and their systems, new portions of buildings and their systems, and new systems and equipment in existing buildings, as well as criteria for determining compliance with these requirements. This standard provides the minimum requirements for energy-efficient design of most buildings, except low-rise residential buildings. Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years.

But I suspect project teams will be able to use more current standards on LEED v3 and v4 projects on a case-by-case basis. USGBC may not create a credit substitution list like they did for v4 into v3. LEED NC v4.1 is in BETA, and is expected to be for the entirety of 2019. LEED NC v4.1 EAc2 requirements are outlined at:

After discussions with top folks within USGBC/GBCI it also sounds like projects with 50%+ unregulated energy use (e.g. Up to 9 points for reducing energy cost and up to 9 points for reducing GHG. LEED v4.1 splits the energy modeling points into two point thresholds - Performance Cost Index (PCI) & greenhouse gas (GHG) emissions. We have a call with GBCI today, since it seems like the language contradicts each other. Appendix G allows the baseline efficiency to be taken from Appendix Table G3.5.1, which is much less stringent than Table 6.8.1. The mandatory provisions point to minimum efficiency tables (e.g.

The interior lighting power allowance can be determined using either Tables G3.7 or G3.8 and the methodology described in Sections 9.5.1 and 9.6.1. Both LEED v4.1 EAp2 & 90.1-2016 Appendix G requires conformance with mandatory provisions listed in Sections 5.4, 6.4, 7.4, 8.4, 9.4, and 10.4.
